Abstract
The present invention provides a tubular surgical cutter fabrication method comprising forming one or more tabs which extend beyond an end of a tube. Each of the tabs is then folded across at least a portion of the end of the tube, and affixed in the folded position to form an end structure extending across the end of the tube. A cutting edge is imposed on the tube adjacent to the end structure, thereby providing a tubular surgical cutter having the structural reinforcement of a closed end without resorting to welding or otherwise attaching a closed end structure about the perimeter of the tube.
